i have this code which brings the alpha value of a mc up to 100, how can it be adapted to bring the alpha down again to 0 once it has hit 100??

any help would be most appreciated.

onClipEvent (load)

{  
\_alpha = 0;  
}

onClipEvent (enterFrame)  
if (\_alpha \< 100) {  
\_alpha++;  
}

onClipEvent (load) {  
\_alpha = 0;  
reached100=false  
}  
onClipEvent (enterFrame) {  
if ((\_alpha\<100) and (reached100==false)){  
\_alpha+=2;  
}  
else {  
if(\_alpha!=0){  
reached100=true  
\_alpha-=2;  
}

```
}

```

}

cheers for that fella, works a treat.

presumambly the most efficient way of slowing down the increase/decrease alpha effect is to play with the ‘\_alpha+=2;’ part of the equation…

this stuff is begining to make more sence
